thats the thing, there are a lot of pastes in there and all are of good quality. even on boutique builders that difference is night and day when they paste it with a good paste instead of the one that came from factory, its a good 5-10c.
You only put numbers that pastes that are available to the consumer purchase dont make difference since the pastes itselves doesnt differ that much (which they do), you dont put the paste that was used at the factory, which are the ones that come in those pesky white tubes (extreme low quality if you used those), nor that the method of application makes any meaningfull impact, which it does.
I wonder how you will counter the old repasting threads showing the job that apple workers done when applying the past and the lowering of the temps due to the repaste.
